Have acer extensa 4420 laptop. The computer works fine, and the CD/DVD drive opens and shuts properly. If I put a CD in there, you can hear the noise that the CD drive would normally make when the disc begins to spin. However the drive does not read the disc, and I dont know whether it is because of a bad disk drive or corrupt driver. I thought that if a disk drive was bad then the light on the drive would keep flashing continuously even after the disc stopped spinning, but that isnt happening here; the light goes on, the disc starts spinning and then when the disk stops spinning the light goes out.

What do you guys think would make the disk drive work properly?

So far I havent tried anything. Im afraid that if I download the driver from the acer site, it may not be the right one, because that did happen once with another computer. If there is nothing else I can do, then I guess I will have to try that. But is there maybe some hardware issue inside, like maybe it doesnt make a good connection with the motherboard, or maybe osmething like a dirty lens (although it looks clean)

The first thing to try is to go into the Device Manager and uninstall the drive and then restart the computer. If there is a bad driver, this will replace it.

If this doesn't work, we will go from there.

While I was waiting I tried that, but I just get a message saying the best driver for your device is already installed'. Then I uninstalled the dvd device and then did scan for hardware changes, and it said device driver installing, after which came another message 'device driver not installed successfully'. The device is optiarc dvd rw ad-7560A ATA Device'

No, thats the thing and in Device manage it had a yellow exclamation mark next to the dvd drive.

I was looking on the internet and I found a solution. It had to do with the upper and lower filters, I deleted them in the registry and then rebooted and now everything works fine. Thanks for working with me on this problem, because knowing that someone else is trying to solve my problem gives me the persistence and also do some research on my own.
